The image of the stunned and weary looking boy, sitting in an orange chair inside an ambulance covered in dust and with blood on his face, encapsulates the horrors inflicted on the war-ravaged northern city and is being widely shared on social media.

A doctor in Aleppo on Thursday identified the boy as 5-year-old Omran Daqneesh. Osama Abu al-Ezz confirmed he was brought to the hospital known as "M10" Wednesday night following an airstrike on the rebel-held neighborhood of Qaterji with head wounds, but no brain injury, and was later discharged.

Rescue workers and journalists arrived at Qaterji shortly after the strike and began pulling victims from the rubble. "We were passing them from one balcony to the other," said photojournalist Mahmoud Raslan, who took the iconic photo. He said he had passed along three lifeless bodies before receiving the wounded boy.

A doctor at M10 later reported eight dead, among them five children. The strike occurred during the sunset call to prayer, around 7:20 pm, said Raslan, a correspondent for Al Jazeera Mubashir.

Omran was rescued along with his three siblings, ages 1, 6, and 11, and his mother and father from the rubble of their partially destroyed apartment building, according to Raslan. None sustained major injuries, but the building collapsed shortly after the family was rescued.

"We sent the younger children immediately to the ambulance, but the 11-year-old girl waited for her mother to be rescued. Her ankle was pinned beneath the rubble," Raslan said.

In the video posted late Wednesday by the Aleppo Media Center, a man is seen plucking the boy away from a chaotic nighttime scene and carrying him inside the ambulance, looking dazed and flat-eyed.

The boy then runs his hand over his blood-covered face, looks at his hands and wipes them on the ambulance chair. Doctors in Aleppo use code names for hospitals, which they say have been systematically targeted by government airstrikes. Abu al-Ezz said they do that "because we are afraid security forces will infiltrate their medical network and target ambulances as they transfer patients from one hospital to another."

Activists living in opposition areas rely on informers in the government-controlled Latakia province to warn residents of impending airstrikes.

The United States has expressed shock at a photo circulating worldwide on social media that shows a dazed Syrian boy covered in blood and dust, calling him "the real face" of the country's war.

"That little boy has never had a day in his life where there hasn't been war, death, destruction, poverty in his own country," State Department spokesman John Kirby told reporters during his daily press briefing.

Since the image's release, the photo has reverberated around the globe, much like that of three-year-old Aylan Kurdi, whose body washed ashore on a Turkish beach last year.

Two people found guilty of “refugee smuggling” that lead to the much-publicised case of the drowning of Syrian toddler Aylan Kurdi and four other refugees were sentenced to four years and two months in prison. Kirby, whose boss John Kerry has for months attempted to forge a pathway with Russia to end the war, said Thursday that "we all have to pull together to try to reach a better outcome."
